With Halloween just a chilly breeze away, pet parents are busily searching for or stitching up clever costumes for their fur babies. And if you are one of the millions of last-minute shoppers, pet suppliers have hot trends ready for you.

According to the National Retail Federation's 2018 Halloween Spending Survey, nearly 20 percent of pet parents plan to dress their pets in costumes this Halloween, up from 16 percent last year. The survey also reports that of the 31.3 million Americans participating in this trend, millennials are most likely to dress their pets in a costume.

Two of the largest pet supply retailers, Petco and PetSmart, are offering a number of inexpensive costumes — most less than $20 — in popular mythological and movie characters from “Star Wars” and superhero comic book series.

Petco has some funny original — the Dirty Puptini, which looks like a collar of shame with olives — the Cheesy Pizza Delivery and French Toast, complete with a Parisian beret. Funny cat costumes include fish and Sushi Roll — and PetSmart even has hamster costumes.

PetSmart reports that among the most popular pet costumes this year are a pumpkin, hot dog, bumble bee, devil, superhero and lion. PetSmart carries these popular costumes and more. New costume arrivals this year include a mermaid,shark and teddy bear. Costumes for small pets like guinea pigs and hamsters remain popular with mermaid, unicorn and superhero options. Or you can keep it simple with a Happy Halloween bandana or a bow tie collar are excellent alternatives for pets who don’t tolerate full-body costumes.

Toys feature Halloween characters like mummies, monsters and skeletons, and treats for this time of year combine chicken and pumpkin spice flavors for dogs.

PetSmart invites costumed pets to the stores from noon-3 p.m. Saturday and Sunday, Oct. 20-21, for the “Who’s Your Boo?” costume parade and event. Prizes will be awarded for the first-, second- and third-place costumes.

Petco also is hosting its annual Make A Scene Photo Contest on Instagram. For a chance to win a $10,000, follow @petco on Instagram, post a photo of your costumed pet in a scene that matches the pet's costume with the hashtag #PetcoHalloweenContest.

Petco also reminds pet parents that the things that make Halloween fun for humans can make it scary for pets. Candy and festive décor can be dangerous for pets, so be sure to keep trick-or-treat candy away from pets, especially chocolate, and raisins. Give them only treats and toys designed for your pet.
